Timothy Genda currently researches formation of fallout in nuclear explosions. In particular, he is interested in how different environmental material impacts the vapor environment of nuclear explosions and resulting radiochemical fractionation in fallout particles. He received a B.S. in Physics from the U.S. Air Force Academy, and an M.S. in Nuclear Engineering from the Air Force Institute of Technology. Tim is also an officer in the AIr Force Reserves, where he provides support for worldwide nuclear treaty monitoring and nuclear forensics operations. Tim also enjoys photography, backpacking, motorcycling, skiing, and mountaineering in his free time.
Jeff Graham studies the manufacture and properties of nano-structured metal composites for use in high-radiation environments. He received his B.S. in Physics from the California Institute of Technology in 2007. Prior to joining the Nuclear Materials Group, he spent ten years as a physicist, program manager, and staff officer for the United States Air Force, and is enjoying having been given an academic development assignment. Left to his own devices, he enjoys Scottish country dancing, Nakamura Ryu Batto-do, backpacking, and craftsmanship.
Joey Kabel is currently researching the micromechanical properties of irradiated SiC/SiC composites for advanced reactor applications; applying SEM, FIB, Xray tomography, nano-indentation, and in situ testing techniques for material characterization. Joey graduated from Washington State University in May 2015 with a B.S. in Materials Science and Engineering. Outside of research he spends time participating in nuclear outreach, snowboarding, and happy hours.
